Active Wheelzoom should enable zoom on pinch and avoid the browsers default action of zooming the viewport.
In other words: zooming YES, viewport zoomed NO.
### Observed behavior
On Firefox (108.0.1 (64-bit)): zooming NO, viewport zoomed YES.
On Webkit (WebKitGTK 2.36.8): zooming YES, viewport zoomed YES.

)
)
fig = figure(
